Soil Bioresource Applications and Environmental Sustainability

-
Image
  Agriculture is the backbone of global food security and rural livelihoods, playing a vital role in economic development, environmental stewardship, and social well-being. Modern agriculture integrates traditional knowledge with scientific innovations to enhance crop productivity, soil fertility, and water-use efficiency while minimizing environmental impacts. Sustainable agricultural practices such as conservation tillage, crop diversification, integrated nutrient management, and precision farming help maintain soil health, conserve biodiversity, and improve resilience to climate change. Advances in biotechnology, digital agriculture, and climate-smart farming enable farmers to optimize inputs, reduce losses, and adapt to changing agro-climatic conditions. Agriculture also contributes to ecosystem services by supporting carbon sequestration, nutrient cycling, and landscape sustainability. By promoting resource-efficient and environmentally responsible farming systems, agriculture...

Belowground Interactions and Implications for Nutrient Use Eco-Efficiency in Cropping Systems

-
Image
  Belowground interactions play a critical role in determining nutrient use eco-efficiency in cropping systems by regulating how plants access, transform, and retain essential nutrients in the soil environment. These interactions involve complex networks among plant roots, soil microorganisms, and soil physical and chemical properties. Root architecture and exudation patterns influence microbial activity by supplying carbon substrates that stimulate beneficial microbes such as mycorrhizal fungi and plant growth–promoting rhizobacteria, which enhance nutrient mobilization, particularly of nitrogen and phosphorus. At the same time, microbial processes such as mineralization, immobilization, and nitrification govern nutrient availability and losses. In diversified cropping systems, including intercropping and crop rotations, complementary root traits and temporal niche differentiation reduce competition and improve overall nutrient capture. Improved belowground biodiversity also enhan...

Microplastics from agricultural mulch films improve soil aggregation and alter microbial communities

-
Image
  Microplastics released from the degradation of agricultural mulch films are increasingly recognized as influential factors in soil systems, with measurable effects on soil aggregation and microbial community structure. As mulch films fragment under ultraviolet radiation, temperature fluctuations, and mechanical disturbance, they generate microplastic particles that become incorporated into soil aggregates. These particles can act as physical binding agents, altering pore structure and promoting the formation of larger, more stable aggregates by interacting with soil organic matter and mineral surfaces. However, this apparent improvement in aggregation does not necessarily equate to enhanced soil health. Microplastics modify soil aeration, water retention, and nutrient diffusion, creating novel microhabitats that selectively favor certain microbial taxa while suppressing others. Changes in microbial diversity, enzyme activity, and functional groups involved in carbon and nutrient ...

Strategies to Reduce Fertilizers: How to Maintain Crop Productivity and Profitability in Agricultural Acidic Soils

-
Image
  Reducing fertilizer inputs while maintaining crop productivity and profitability in acidic agricultural soils requires an integrated soil and nutrient management approach. One effective strategy is correcting soil acidity through the application of lime or other alkaline amendments, which improves nutrient availability, reduces aluminum toxicity, and enhances root growth, allowing crops to use applied nutrients more efficiently. Adopting site-specific nutrient management based on soil testing helps optimize fertilizer rates and avoid unnecessary applications. Integrating organic amendments such as compost, farmyard manure, green manure, and biochar improves soil structure, increases cation exchange capacity, and enhances nutrient retention in acidic soils. The use of acid-tolerant crop varieties and diversified crop rotations, including legumes, supports biological nitrogen fixation and reduces dependence on synthetic nitrogen fertilizers. Precision farming tools, split fertilize...
